If the hydraulic system is compared to the human body, then the hydraulic oil is equal to human blood. In the hydraulic system, the hydraulic oil plays a role in energy transmission, system lubrication, and prevention Urumqi orbit motor The functions of corrosion, rust prevention and cooling, and whether the hydraulic system can work effectively are closely related to the type and selection of hydraulic oil. Coding, composition and characteristics of hydraulic system: high purity general machine tool oil, refined mineral lubricating oil, with good rust resistance and oxidation resistance. High wear resistant hydraulic oil, refined mineral lubricating oil, rust proof, anti-oxidation, anti-wear. High temperature and high pressure hydraulic oil, with the characteristics of rust prevention, oxidation resistance, wear resistance, etc., is refined into mining lubricating oil, and added with viscosifier. Refined mining lubricating oil HG hydraulic guide oil, rust proof, anti-oxidation, anti-wear, anti stick slip. HS synthesis customized orbit motor Hydrocarbon is a kind of low temperature hydraulic oil, which has the characteristics of anti-oxidation and anti-wear.
What is the oil supply mode of the hydraulic pump? The straight shaft swashplate plunger pump can be divided into two types: self suction type and pressurized type. Most high-pressure oil supply hydraulic pumps use pneumatic oil tank, and some hydraulic pumps are also equipped with oil make-up slave pump to deliver pressure oil to the oil inlet of the hydraulic pump. The self-priming pump has the characteristics of strong self-priming ability and no need for external oil supply customized orbit motor . Bearing for hydraulic pump. The most important part of the plunger pump is the bearing. If the bearing has clearance, the normal clearance of the three pairs of friction pairs inside the hydraulic pump cannot be guaranteed. At the same time, the hydrostatic support oil film thickness of each friction pair will be damaged, thus reducing the service life of the plunger pump bearing. According to the data provided by the manufacturer of the hydraulic pump, the average service life of the bearing is 10000 hours. If this value is exceeded, a new port shall be replaced. 3、 Conclusion. The service life of the piston pump is related to the maintenance at ordinary times, the quantity and quality of the hydraulic oil, and the cleanliness of the oil. At the same time, avoid orbit motor manufactor The particles in the oil will wear the friction pair of the plunger pump, which is also an effective method to extend its service life.
Functions: It is used for the storage, supply and recovery of hydraulic media, the connection between hydraulic components and the transmission of energy carrying hydraulic media, filtering impurities in the hydraulic media, keeping the media required for the normal operation of the system clean, heating or cooling the system, storing and releasing hydraulic energy or absorbing hydraulic pulsation and impact, and displaying the pressure and oil temperature of the system; Hydraulic working medium: various hydraulic oils (fluids), efficacy: as the energy carrying medium of the system, it plays the role of lubrication and cooling while transferring energy. Generally speaking, the hydraulic components that can complete certain specific functions are called hydraulic circuits. In order to meet the working requirements of certain machinery or equipment, the overall structure of several special basic functional circuits connected or combined together is called hydraulic system.
During the operation of hydraulic transmission, the hydraulic actuator can be adjusted steplessly in a large range by adjusting the control valve, and the speed range can reach 2000 meters. Good operation ability and rapidity. The liquid is elastic and can absorb impact, so the hydraulic transmission movement is even and stable; It is easy to realize fast starting, braking and frequent reversing. Reciprocating rotation customized orbit motor The reversing frequency of rotary motion can reach 500 times/minute, and the reciprocating linear motion can reach 1000 times/minute. It is easy to control operation and realize overload protection. The hydraulic system with convenient operation and control is convenient for automatic control, remote control and overload protection; Automatic lubrication during operation, which is beneficial to Urumqi manufactor Heat dissipation, prolong service life. It is convenient for automation and electromechanical hydraulic integration. Hydraulic technology is easy to combine with electronic control and electronic control technology to form an electromechanical hydraulic integration composite system to realize automatic cycle work.
